Series II Transmission + Series I Engine?

so you guys know i got a1995sc riv with 113000 on it now.I am pretty sure the trans is on it way out cause it slips a little bit every now and then. i found a 1997 sc park ave they just got in at the junk yard the car runs and drives find and they $400 for the trans but will it work for the riv. taking that my car is a series 1 if not will the trans from a 1995 na riv since that has a series 2 in it too?

The 97 trans would be preferable, but I'm not sure what would be involved in the swap. The 95 NA Riv trans should be same as yours, I'd think.

anybody else got ideas on this? if i do got the trans from the park ave should i mess with the pcm in mine in cause i have no idea if the shift points are the same or not or just get the pcm from the p.a.?

Not sure how you could do it on your year. Unless GM Tuners could change up the trans parameters. The hangup on your year would be adding the 5-7 wires to the pcm from new trans connector and programming.

so i have to get the pcm from the park ave?

My 95 started slipping in first gear two months ago. I found tranny fluid in the lines connected to the vacuum modulator, a break in the vacuum lines off the throttle body and the tranny fluid was a few quarts low. I changed the modulator, replaced the vacuum lines and added fluid.

The tranny has been working great for two months now.

Is there any way to put a 4t65e-hd tranny on a series I motor?

Will crazy glue work? lol

bump'

You can physically bolt it up. Yes, it's the same in that respect.

Torque converter sizing should be checked 4T65HD's had 258mm converters.

Programming to control the trans will be the toughest part. When I helped Oldsman convert from a 96 4T60 to a 98 4T65 we needed to add 5 wires and change to a 97 pcm for ease of programming. Not sure being a 95 with totally different wiring how you'd control it. That pcm was never intended to controll that transmission.

As the late Billy mays would say. Mighty putty

sorry for bumping an old thread, but I hadn't said thanks to bill for his response yet, and so, thanks bill, haha, I think i'll avoid any complicated wiring / computer modifications to make that work., going to try to piece together a 4t60e and get the old girl back on the road.

i think the 4T65HD has a different size flywheel also. than your 1995 trans. look at some other post, cuz i dont think this can done without highly mods.
